Has anyone ever had the parking brake dash valve freeze? PP-DC type valve. This afternoon the valve would not push in to release after sitting in below zero all day. After a few tries it made a crunch sound, kinda like breaking plastic and then seemed fine. Another older bus with the PP-1 style valve had the same issue today. We will check the air driers. But this is a new issue. Ideas? Comments?
